149962 - Miller S-64/S-74 Drive Roll Carrier Spacer Kit (Pack of 2)

Keep Your Miller Feeder Running Smoothly

Every welder knows that a smooth wire feed is the heartbeat of a good MIG weld. If your wire is slipping, dragging, or feeding inconsistently, it can ruin your bead and waste valuable time. Often, the issue isn't the machine itself but the small components inside the drive assembly. The Miller 149962 Spacer, Carrier Drive Roll is a small but mighty part that plays a huge role in how your S-64 or S-74 wire feeder performs. This package of two spacers is designed to keep your drive rolls perfectly aligned, ensuring that the wire is gripped and pushed through the liner with precision.

When you are out in the shop or on a job site, you need your equipment to work as hard as you do. The S-64 and S-74 series feeders are workhorses, but even the toughest machines need maintenance. If you have taken your feeder apart to clean it or change drive rolls, you know how easy it is for small spacers and washers to get lost or worn out. Reassembling your feeder without the correct spacer—or using a makeshift solution—can lead to alignment headaches that cause wire shaving and feeding jams. By using genuine Miller replacement parts, you guarantee that your machine fits together exactly as the engineers intended.

This kit comes with two spacers, which is perfect because it allows you to refresh the assembly completely or have a backup ready in your toolbox. Installing them is quick and easy, getting you back under the hood and welding in no time. Don't let a ten-cent problem cause a hundred-dollar downtime. Ensuring your drive roll carrier is spaced correctly helps prevent premature wear on your expensive drive rolls and keeps the wire centered for the best possible electrical contact and arc stability.

Whether you are doing routine maintenance or fixing a breakdown, trust in genuine Miller parts. The 149962 spacer is built to the high standards you expect from Miller Electric, providing the durability and fitment you need to keep your arcs hot and your welds strong. Add this 2-pack to your maintenance kit today and ensure your S-series feeder continues to deliver the reliable performance you rely on.
